Plaxis - How To Simulate Pile Static Load Test

[@jiayaowang]

Hello, thank you so much for the tutorial. I have a question, how did you assign pile material? 11:14 in the video

[@geotechniq]

You can check at 6:10 in the video, the concrete pile is modeled as linear elastic with concrete properties.

[@geotechniq]

And to assign the pile material you just drag and drop same as when you assign the soil layer.

[@DolleyAlskaf]

I want to apply my load as a point load with vertical and horizontal components. Do I need to divide it by the diameter of my pile in this case?

[@vinodchoppari9609]

Thank you.sir please make a video on piled raft foundation

[@rahuldogra5282]

Have you made it???

[@geotechniq]

Thanks for your suggestion. I will make it when appropriate.

[@geotechniq]

I'm doing it. Comming soon.

[@user-of7uz6vc6r]

Hello, in the video, you applied a line load at the pile top and used axisymmetric models to simulate a pile load test. I have a concern regarding the values of the line loads you calculated. Following PLAXIS manuals, the force should be represented by force per unit radian. However, you calculated force per unit width. Is it correct?

[@paulmavundla1941]

Thank you. This is a great video!

[@luisamariareyes6795]

Hey, thank you for your videos. I wanna know how could I calculate only the end bearing? Could you please make a video about this? (shaft resistance and end bearing) how to know the results separately

[@geotechniq]

Thanks for your comment, I will try to figure it out.

[@geotechniq]

This video is to simulate the static load test, from the test results we can evaluate the pile bearing capacity generally according to the Code. But I think we can calculate the pile shaft resistance and pile tip resistance also, let try to find it.

can you explain pls how to calculate the pile bearing and shaft friction?

Actually, I didn't did it. But I will try when have free time. Btw thank you for watching.

What about strip footing rseting on a slope??

[@geotechniq]

Check load-settlement curve, you can make it.

can we see the graph in plaxis?

It is just a simple excel file, you can make it too. If not, please send the request via email [e-mail]

[@geotechniq]

Sorry, I didn't check the comment for over 2 years :) Hope you already found it.

[@geotechniq]

Do you have any actuall test results, then we will try it.

[@abhiii.05]

@@geotechniq Hi, i tried that on Plaxis 2D.

[@geotechniq]

@@abhiii.05 So, how was the result? Is it good?

[@abhiii.05]

@@geotechniq yeah it was almost similar to experimental results (site results)

[@muhammadfaizanmalik3303]

Is it a load displacement curve?

[@sagantisharathsai8216]

1) can't we apply the point load Directly why to convert it in kN/m2 2)pile bearing and shaft resistance calculations

[@geotechniq]

1) Technically, I think it is possible in this case. 2) Actually, I didn't did it. But I will try when have free time.

[@geotechniq]

Thanks

[@geotechniq]

Hi friend. In this case, we can not use point directly. because the pile is modeled same as soil layer with properties of concrete, it is not a plate. Then point load can't be applied for this case.

[@subhabratadey6527]

If I create this in 3D plaxis , do I need to create the half geometry only to get the same load settlement results?

[@geotechniq]

actually, I didn't try plasix 3D, But I guess you don't need to model 1/2 the geometry while using Plaxis 3D.

[@captainsmollett3173]

If the drawn pile has a diameter of 0.25 m, why are you loading the full pressure stage and not half?

[@geotechniq]

This is the simulation of actual static load test.

[@geotechniq]

You can check the loading value in the excel file I attached at the download link.

[@salsabilaassegaf8318]

Hi, can you explain how to convert the Load (kN) to q (kN/m/m) ? Thankyou

[@geotechniq]

Just think about the unit, kN -> kN/m/m.

[@Hy_Jay]

It is simple, Stress = Load / Area. Now, you can calculate the pile area using pi*radius squares. So just divide load with area you will get intensity. This values are round up.

[@2btns920]

Why didn't you use plate element to model pile?

[@geotechniq]

Good question, but you should try first then you can understand why.

[@SaifulIslam-yh7fn]

But how yo derive pile capacity from the curve?

[@geotechniq]

You should refer to the code, check the limit settlement of that Code

[@geotechniq]

maybe 10% of pile diameter or 10mm, 20mm, depends on the code in your country.

[@juliansandoval8022]

@@geotechniq You can also use Davisson criteria. And dont forget to compare the plaxis results with the actual results of the static load test

[@geotechniq]

@@juliansandoval8022 Thank you. I'm about to make a video to evaluate static load test results using Davisson criteria.

[@janmihalik6079]

Why the pile is drawn on the edge of the model, does not reflect the strain (stress) from the edges of the model ?

[@geotechniq]

This is static load test, why do you need dynamic load?
